Walter Ulbrich (15 June 1910 – 13 November 1991) was a German film producer primarily known for writing and/or producing 10 of 16 four-part adventure mini-series made for West German TV in the 1960s and 1970s. Mostly based on classics of world literature such as Robinson Crusoe or The Sea Wolf, these West German/French co-productions traditionally premiered on West German public-service television in December and are therefore also known as Weihnachtsvierteiler (Christmas four-parters). The series have been dubbed into a variety of languages and also became popular outside Germany, especially in France, the UK, and Canada.
